Ultraviolet (UV) light is electromagnetic radiation of wavelengths of 10–400 nanometers, shorter than that of visible light, but longer than X-rays. UV radiation is present in sunlight, and constitutes about 10% of the total electromagnetic radiation output from the Sun.
23 wrz 2024 · Ultraviolet (UV) radiation is undetectable by the human eye, although, when it falls on certain materials, it may cause them to fluoresce—i.e., emit electromagnetic radiation of lower energy, such as visible light.
UV radiation is part of the solar spectrum that can damage the skin and eyes. Learn about the three types of UV radiation (UVA, UVB and UVC), how they differ in wavelength, biological activity and penetration, and how they are affected by environmental factors.
24 sie 2023 · Ultraviolet (UV) radiation is one part of the electromagnetic spectrum of radiation that reaches Earth from the sun. It is a form of light energy situated on the spectrum just beyond...
Ultraviolet radiation is a form of energy from the sun that affects life on Earth. Learn how UV-B radiation damages DNA, how ozone protects us, and how human activities change the UV levels.
1 kwi 2023 · Ultraviolet light is electromagnetic radiation in the wavelength range of 10 to 400 nanometers, which is between x-rays and visible light. Learn about the types, sources, effects, and uses of UV light, and how it relates to the ozone layer and human health.
29 lip 2024 · Ultraviolet (UV) radiation covers the wavelength range of 100–400 nm, which is a higher frequency and lower wavelength than visible light. UV radiation comes naturally from the sun, but it can also be created by artificial sources used in industry, commerce and recreation.
